BFC237178333

The BFC237178333 is a metallized polyester film capacitor from Vishay BCcomponents, part of the MKT371 series. It offers a capacitance of 0.033 µF with a tolerance of ±10% and a rated DC voltage of 250 V. The capacitor is designed for general purpose applications such as blocking, coupling, bypass, and energy reservoir.

Electrical characteristics include a maximum tangent of loss angle of 75×10⁻⁴ at 1 kHz, 130×10⁻⁴ at 10 kHz, and 250×10⁻⁴ at 100 kHz. Insulation resistance exceeds 30,000 MΩ (measured at 100 V for 1 minute). The capacitor can withstand 400 VDC for 1 minute between leads, and 500 VDC between leads and case. The rated voltage pulse slope is 70 V/µs at 250 VDC.

Encapsulation uses a flame retardant plastic case and epoxy resin with UL 94 V-0 rating. The component is rated for operation from -55°C to +105°C, with a rated temperature of 85°C. It is a through-hole device with radial package, PC pin termination, and 7.62 mm lead spacing. Lead material is tinned wire, and lead length is 4.0 mm +1.0/-0.5 mm.

This capacitor meets climatic testing class 55/105/56 per IEC 60068-1 and is classified as performance grade 1 (long life). It is reference standard IEC 60384-2 compliant.
